KuroMaii made an Arduino and Wii Nunchuck based gyroscope mouse imitation.
I can say that is one of the smoothest gyro mouse's i've seen. The "WiiChuck" adapter and functions code for Arduino came from TodBot.
herctrap used an arduino to read from the LFS (Live For Speed) game data such as rpm, speed, gear, turbo pressure, and fuel and made his own dashboard.
From the data he aquired he used 1 servo for the fuel indicator and a unipolar motor for the rpm that actuates also a shift light and one for the fuel indicator. The dashboard completes a 2x16 LCD screen showing current speed and current gear.
Tharit Bunteongjit demonstrates his project Sensibility Space: Ambient Space Controls through Facial Expression.
In his own words "In Sensibility Space+, the experimental project of the concept, the system can sense simple human emotions through facial expression from image processing and analysis with OpenCV in Processing to ident...
David Resnick choose a rather complex project for his first-year project in the Arts Computation Engineering program at UC Irvine. The overall goal of Undulating Flux is to bring the participant into what psychologist Mihalyi Csikszentmihalyi termed a flow state. A flow state is described as a state of being wherein action follows upon action according to an internal logic that seems to need no consc...
robidouille wanted a robot being able move on a horizontal wooden 2 by 4 stud and avoid obstacles found in its way. After several designs he ended up with this 2 arm version that seems to work the best. He is using an Arduino as microcontroller and a couple of Hitec HS322-HD servos. Each arm has 2 lever-switches to detect pressure in front and below. The design looks like a monkey but it works so well i don't see any danger.
Mark Czubin and Domien Nowicki present their project for Mobile & Pervasive Computing at Hasselt University.
Mounted on the glove is an Arduino board with an accelerometer, flex sensor and infrared led, the infrared led is seen by the wiimote, and is used for tracking finger motion. The flex sensor is used for shooting and the accelerometer for reloading, last the communication between glove and laptop is done through an XBee module. I can't wait to see this with a first person shooter game.
Dino Magri, Pedro Ângelo, Ricardo Lobo and Tiago Serra took some cheapo rc cars, ripped out the original pcb and replaced them with arduino in order to drive them with GameCube steering wheel controllers. Next they made a rather large circuit to drive their cars around and voila, a new MicroMachines racing game was born! Of course they couldn't bend to see the cars so the track is viewed via a projector on the wall. The whole thing is amazing but i cant say the same for the driving skills. :). If you want the documentation and the code you can check here with only requirement you know portuguese. If you're interested in the teams works you can check these sites also, labcdmusaxdatelier.
Alain V. made a simple project with an RFID reader attached to an arduino microcontroller which sends the commands to a pc and enables him by selecting different cards or tokens to start play a playlist or stop it. Nice, simple and does the job with a hi-tech touch. You can find all the info you need here.
